二氨基二苯基羧酸盐的合成与表征

Synthesis and characterization or diaminodiphenyl carbxylate

以对氨基苯甲酸与二价金属氧化物（或氢氧化物）合成了一系列含不同金属元素（Ｍｇ，Ｃａ，Ｓｒ，Ｂａ，Ｐｂ，Ｃｏ，Ｎｉ）的二胺，采用元素分析，ＩＲ和１ＨＮＭＲ对其结构进行了表征，测定了它们在水中和ＤＭＦ中的电导率，并以ＴＧ－ＤＴＡ研究了其热性能。结果表明，这类二胺具有较好的耐热性，在ＤＭＦ等有机溶剂中为弱电解质，可作耐热高聚物的单体。

A series of metal-containing(Mg,Ca,Sr,Ba.Ph,Co,Ni) diamines were prepared by reacting paminobenzoic acid with divalent metal oxide or hydroxide. Their structures were characterized by elemental analysis,IR and 1HNMR,and their electroconductivity and thermal properties were also investigated.It was found that these diamines are weak electrolytes in DMF with high thermal stability and may be used for the preparation of some heat-resistance polymers.
